Radioactive? (Arcs)

so I've built a strange kind of tesla, which is powered only by nem zeilentrafo and has only a a cell a 2000V capacitor and a simple fuckenstrecke.

It come to ca 3-4 cm discharges it out (not more really high-frequency capacitance through are the high
so now the question: If  HV electrical  one that end up closer together, lights one of the wire ends strong black. The radioactivity normally not seen, I know. But that is just about as: +++
I wanted to know whether the only different wavy light is or could be if there what malicious it only once. There's nothing radioactive, that is only normal ionized copper steam that turns greenish blue. Look on Google for flame coloring. The green color comes when the current is relatively high because of the copper surface neatly met Alp article be removed and burned. Jop, that is the flame due to the copper, because there are so a blue powder (forgot the name) if one holds it over a flame, värbt green. There are also other metals where the color will be different.
I wondered if an ARC produces X ray. Copper(ii) chloride or copper will be the blue powder. However, it funzt with the chloride significantly better and there is also no sulfur trioxide. So you can see it also. Chlorine is me personally rather than sulfur trioxide. Both stinks to heaven, is both toxic and you should not overdo it with both.

The sticking point is in my eyes, that the flame coloration with the chloride funzt much better than with the sulphate (which is anyway necessary to moisten with HCl and where also the chloride is produced).

ughhhh moisten with HCl? het even if you raise the electrode and into the salt then appears...
by the way: If you mix ammonium chloride and copper sulphate and then just shows the hot electrode and pulls then an arc so that then discolors da sganze black and joins. CuSO4-> grüün
NH4Cl-> turquoise
HNO3-> bluish violet
NH3-> blue-violett
Al-> light blue
CU-> grüün
NaCl-> yellow
NaCO3-> yellow
NaHCO3-> yellow xD
NH4HNO3-> blue-violett
KNO3-> orange
H2SO4-> light blue
I2lsg-> white
I now go try iodine...I'm interested ercht that will look like...
also I'm in next time time a gas discharge tube with N2O.
